Background and Objective : In an orbital fracture involving diplopia, enophthalmos is a major problem to be corrected
because of soft tissue swelling and limited incision, which causes inaccurate restoration of orbital anatomy and reestablishing
orbital volume. Pre-operative computerized planning combined with intra-operative navigation and endoscopy are used to
create the accurate anatomical orbital position and effectively correct the posttraumatic diplopia and enophthalmos.
Case Report : An 18-year-old Thai male with diplopia and enophthalmos presented a posttraumatic left orbital fracture two
months prior. Three-dimensional CT scan of the facial bone confirmed the fracture. The patient required surgical treatment
for correction of the orbital fracture. The intra-operative navigator and endoscopy-assisted technique were used. Pre- and
post-operative pictures were compared, indicated the successful correction of enophthalmos and clinical correction of
diplopia.
Conclusion : Intra-operative navigator combined with endoscopy-assisted technique were a new surgical procedure that
could correct the orbital deformity problem involving enophthalmos and diplopia more effective.
